RESUMO
Objective To analyze the risk factors for postoperative nosocomial infections in the department of otorhinolaryngology,and provide guidance on improving the quality of life for patients.Methods The clinical data of the patients tmdergoing surgical procedure in the department of otorhinolaryngology form January 2011 to December 2016 were reviewed to identify the potential risk factors of nosocomial infections.Chi-square test and multivariate logistic regression model were used for the analysis.Results A total of 152 (2.25％) cases of nosocomial infection were identified in 6 753 cases of surgical operation.Univariate analysis revealed that sex,age,length of stay,patient referral,class of surgical wounds,length of operation,and complications were related to postoperative nosocomial infections.The patients without nosocomial infection showed higher cure rate than those complicated with nosocomial infection (P＜0.05).Multivariate logistic regression analysis identified that male (OR=2.831,95％ CI:1.758-4.558),older (OR=5.833,95％ CI:4.491-7.577),patient referral (OR=1.790,95％ CI:1.008-3.178),higher class of surgical wound contamination (OR=34.866 for Class Ⅰ,OR=2 120.995 for Class Ⅱ,and OR=43 917.453 for Class Ⅲ wounds),and longer length of operation (OR=9.384,95％ CI:18.168-47.525) were the independent risk factors for postoperative nosocomial infections in the department of otorhinolaryngology.Conclusions Multiple risk factors are associated with postoperative nosocomial infections in the department of otorhinolaryngology.Integrated measures must be taken for prevention and control of nosocomial infections based on the specific conditions of the patient.
RESUMO
Objective To evaluate the diagnostic value of sympathetic skin response(SSR)in patients with vestibular vertigo.Methods SSR tests were performed on 1 20 patients with acute vestibular system vertigo,including 70 cases of central vertigo and 50 eases of peripherM vertigo.60 healthy subjects were also examined to serve as controls.Results In those with central vertigo,the abnormality rate in the SSR results was 87.1%(61/70).SSR latency was longer and its amplitude wag lower than in those with peripheral vertigo and in the heMthy controls.In those with peripheral vertigo the abnormality rate was 18.0%(9/50),but the average latency and amplitude were not significantly different from those of the healthy controls.Conclusion Persons with acute central vestibular vertigo may have sympathetic nerve dysfunction.SSR test results can be used as an electrophysiological index to distinguish central from peripheral vestibular vertigo.
